Jennifer Lopez is supposedly “getting tired” of her boyfriend.

The 44-year-old singer has been dating her former backup dancer Casper Smart since October 2011.

Rumours recently emerged via Casper has been sexting with a transsexual behind Jennifer’s back and the songstress is said to be infuriated with the hearsay.

“Jennifer is getting tired of all these allegations,” a source told Page Six. “She doesn’t need this drama and is ready to move on.”

This is the second time Casper has been accused of flirting with transsexual models.

Jennifer is currently preparing to put on a free concert for thousands of people in her native New York City community, The Bronx.

And she also announced a community health initiative which is sponsored by her charitable organisation, Lopez Family Foundation.

Apparently rumours of Casper’s alleged sexual flirtations are taking precedent over Jennifer’s professional efforts.

“She’s coming back to The Bronx and the only thing anyone can talk about is her toyboy and the transsexuals,” a second insider revealed.

“The focus should be on her work for the foundation and the concert, not Casper Smart.”

Jennifer has been married three times, most recently splitting from fellow singer Marc Anthony after seven years of marriage in 2012.

A few months after separating from Marc she began dating Casper.

Jennifer recently spoke about how she he uses wisdom from previous failed affairs to keep her love life fresh.

“As women we can sometimes give ourselves away,” she told People magazine.

"I was certainly guilty of that for some time. Now I realise I am good on my own, so now I can share my life with somebody."
